HOWARD S. MCMILLIN, OF ST. PAUL, MINNESOTA.

KNOCKDOWN COTTAGE.

Specification of Letters Patent.

Patented July 25, 1911.

Original application filed September 20, 1909, Serial No. 518,461.Divided and. this application filed July 11, 1910. Serial No. 571,414.

To all whom it may concern:

Be it known that I, HOWARD S. MOM LIN, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented certain new and useful Improvements in Knockdown Cottages,of which the following is a specification.

My invention relates to improvements in tent or cottage constructionwherein the roof or walls are canvas or equivalent material and consistsparticularly in an improved construction of framework and an improvedmethod of securing the roof and wall covering thereon to provide forefiicient ventilation and to effectively prevent leaking of water intothe interior and also prevent tearing of the covering by shrinkage dueto the same becoming wet, this application being divisional of myapplication filed September 20, 1909, Serial Number 518,461.

In the accompanying drawings forming part of this specification, Figure1 is a perspective View of my improved cottage; Fig. 2 is a similar viewof the same broken away and illustrating the operation of part of theroof supporting mechanism; Fig. 3 is a section in detail of. one of theroof supports; Fig. 4 is a side elevation of the same; Fig. is an endview of the framework broken away; and Fig. 6 is a perspective view ofone end of the cottage with the outer roof removed.

In the drawings the side walls are shown composed of a number of metalsections 2, suitably connected together and carrying connected roofsections 3 forming a support for the inner roof 4, the wall sectionsforming a support for the walls 5 of canvas or other suitable material.The end wall 6 of the roof and the side edges of the roof are suitablyconnected to the wall sections 5 as by the overlapping flaps 7, whichmay be secured together by buttons 8. The meeting edges of the end andside walls are likewise suitably connected together. For the purpose ofsupporting the supplemental roof or fly B I support above the roofsections 3 by means of end standards 9 a suitable ridge pole 10, andsupport at the outer ends of the roof sections eaves supporting bars 11.The bars are each centrally connected with the adjacent horizontal bar12 of the side wall of the framework by an arm 13 which arm has looseslot and pin connection 14 with the bar 12. Thus the arm 13 may be swungupwardly springing the center of the bar 11 with it. The object of thisis to compensate for the shrinkage of the fly roof as indicated by thefull and dotted lines in Fig. 2. As the outer or fly roof shrinks, aswhen it is wet, it will assume the full line position shown in Fig. 2 bythe swinging upwardly of the arms 13 and springing of the eaves bar 11,thus preventing tearing. The roof frame 3 is preferably supported andstrengthened by suitable corner brackets 15 secured over the corners ofthe frame sec tions and each formed with an upwardly extending flange 16arranged to fit against and support the .roof framework 3.

The inner roof 4 is formed with suitable screen ventilating openings 17to allow circulation of air through the interior of the tent, anypassage of rain through said ventilating openings being prevented by thefly roof B. In addition to forming a protection againstthe rain the flyroof being spaced from the inner roof in the manner shown also protectsthe interior of the cottage from the heat. By having the roof and wallcoverings buttoned upon the framework as shown and also formed ofsections buttoned together it will be evident that the same may beeasily unbuttoned and raised from the bottom or lowered from the top orany one side may be removed without disturbing the remaining portion ofthe wall and roof coverings and thus may be easily and quickly convertedinto a partially open construction.

The wall sections as shown are preferably made of angle iron so thatscreening may be easily and simply supported therein so that a frameworkof the maximum strength and rigidity may be obtained.

\Vhere necessary to hold down the eaves bar 11 to prevent it from beingswung upwardly by wind, I provide a spring 18 connected at one end withthe eaves bar and at its other end, as by suitable cord 19, with thelower portion of the adjacent side wall section.

I claim as my invention:

1. In a knockdown cottage comprising wall sections and a roof support, aroof covering said support, a supplementary roof centrally supportedabove said main roof, eaves bars supporting said supplementary roof atpoints outside the side wall sections, the ends of said eaves bars beingrigidly connected with the adjacent ends of said wall 2. In a knockdowncottage of the class described comprising wall sections and aroofsupport, a roof covering said support, an interspaced supplementary roofsupported above said main roof, means for supporting the outer edges ofsaid supplementary roof comprising arms extending downward rigidly fromthe ends of each side wall section, eaves bars connecting the ends ofsaid arms, and an arm hingedly connecting each eaves bar and theadjacent wall section intermediate of said rigid arms.

3. In a knockdown cottage of the class described comprising Wall androof sections, a covering roof for said roof sections, rigid armsextending downwardly in alinement from said root sections at the ends ofthe side wall sections, a supplementary roof arranged above said mainroof and supported at its outer edges by the ends of said projectingroof supporting arms, and a yielding connection between the outer edgeof said supplementary root and adjacent wall sections intermediate ofits ends for the purpose set forth.

4. In a knockdown cottage comprising wall sections, a roof supportthereon, a roof covering said support, a supplementary roo't' supportedabove said main roof and extending downwardly beyond the side wallsections, means for fixedly supporting the outer edges of thesupplementary rooI at a point outside the corners of the side wallsections,

l and means for int-ermediately yieldingly supporting the outer edges ofthe roof from the wall sections. 40

In testimony whereof I aitix my signature in presence of two witnesses.
